Thuringia, Germany; vested in the Allen Proparty Custodian Application July 13, 1938, Serial No. 219,078 In Germany July 15, 1937 6 Claims.

This invention relates to typewriting-account ing machines, sometimes referred to as booking, or bookkeeping machines, and is more especially directed to the means whereby such machines are conditioned to automatically print the calculated totals from the column and from the cross footer totalizers, digit by digit, clearing the totalizers in the process.

Such mechanisms have already become known but have the drawback that it is diflicult to equip a machine for cross total taking which is constructed for vertical total taking only.

According to the invention, these drawbacks are eliminated as follows:

A manually operated controlling or total-conditioning member for the cross totalisers, and a manually operated controlling or total conditioning member for the column totalisers, connect, through a universal member, a driving member which performs the total-taking operation, to a source of power, and locking members holding the controlling members in their active position are arranged to be moved into their active positions with respect to a universal part which is preferably influenced by the movement of the paper carriage, when the controlling members are moved into such active position.

By providing the universal elements aforesaid, disassembling is facilitated.

In the drawings a constructional example of the invention is illustrated.

Fig. 13 is another perspective view supplement-' General description of the machine The principal parts of the machine are the frame I (Figs. 1 and 2) which supports the typewriting mechanism, and the paper carriage, not shown. On the suspension rail 8 secured to the paper carriage, the column totalisers 2 to 5 and the dummy totalisers 6 and 1 (Figs. 1, 1a, 2, 5, and 6) are arranged. A wall 9 (Figs. 1 to 6) which supports a calculating mechanism, is arranged behind the keyboards of the machine. A slotted table In is arranged at the right-hand side of the machine below the suspension rail 8, and secured by suitable means to the machine frame. A slide II (Figs. 2 and is mounted to reciprocate longitudinally in the slot of the table. On this slide II, the cross totalisers I2 and I3 are adjustably secured. Pick up bars I4 and I5 connected with the respective cross totalisers I2 and I3 are engageable by that column totaliser )which is in active position at the time, to shift the 'cross totalisers relatively to their respective master wheels 35, 36.

Mounted in the machine frame I (Figs, 1 and 3) are the keys Ii of a typewriting keyboard, with carriage shift keys I1, and a carriage return key ll. A sub-frame I! (Fig. 1) iorms a further part of the machine, in which frame are mounted a calculating keyboard 20, a set of decimal tabulator keys 2I, a column total taking key 22 (Figs. l, 3 and 7), a cross total taking key 23 for the cross totalisers (Figs. 1, 3, and A motor 24 secured to the right-hand side of the machine frame operates, through suitable gearing, to drive various elements of the type'writing-calculating machine.

The normal calculating and typewriting operation: for the entries required in columns I to IV of the form Fig. 16

For this operation, the column totalisers 2 to I are adjusted on the suspension rail 8 in positions corresponding to the columns I to VI of form 25 (Fig. 16). The tabulator carriage stops allotted to the column totalisers but not shown are adjusted on the usual stop bar.

At the same time, the cross totalisers l2 and II are adjusted and secured on the slide II in the required positions with respect to the column totalisers, or the master wheels. The adjusting and securing operations, however, are performed by the cooperation of a clip 28 (Fig. 5) swingable around a pivot 21 under the influence of a spring 28, with an undercut bar 29 secured to the slide I I. The clip 28 is moved out or clamping position with respect to the undercut bar in the usual manner by its handle 30. After the cross totaliser has been placed in position, it may be held where adjusted by a locking member 3| placed before the handle 30. A nose 32 formed on the handle engages, in the clamping position of the clip 28, a tooth space in a rack 33 secured on the slide I I (Fig. 5) which is just opposite the nose, and thereby-the cross totaliser, or cross totalisers, are held in their positions, as adjusted. For this purpose, the pitch of the rack is, as usually, selected in conformity with the steps of the carriage feed.

The cross totalisers I2 and I3 together form a complementary totaliser or unit K (Fig. 1:1), as will be explained more fully below. To this end, the sequence of the numbers on the numeral wheels of the cross totaliser I2 is the reverse of that on the numeral wheels of the cross totaliser I3. The cross totaliser I2 at the left is positive, and the totaliser I3 at the right is negative. In consequence thereof, a total is taken by subtraction in the positive totaliser I2, and a total indicated in positive form may be taken by addition in the negative totaliser II.

The form 25 is placed around the platen in conformity with the position of the column totalisers 2 to I, and with its first line in position to be typed. Thereupon, the paper carriage is moved into its final position at the right, for instance, by depressing the carriage return key I0.

In the booking example which will be described. the items of the same kind to be entered in the columns I and III of the form 25 which are indicated and added in the column totalisers 2 and 4, are calculated in positive form in the cross totaliser I2, and the corresponding complementary value appears in the cross totaliser I3. The values to be written down in the columns II and IV of the form are indicated and added in the corresponding column totalisers, and in the cross totaliser I3, but are entered, subtractively, into the cross totaliser I2. Due to the fact that the credit items in columns II and IV are introduced in opposite direction to the debit items in columns I and III, the balance is found which may appear on the debit or credit side, i. e., in the column V or VI of the form 25, in conformity with the ratio of the debit and credit items. That cross totaliser in which the balance then appears, is thereupon placed in cooperative position to the corresponding dummy totaliser 8 or I, in a manner to be described more fully, by operating that decimal tabulator key 2| which corresponds to the amount of this balance, whereupon the automatic clear writing of the corresponding cross totaliser I2 or I3 forming part of the complementary totaliser unit K can be printed digit by digit in the column V or VI 01 the form.

In order to effect the bookings in the columns I to IV of the form 25, for example, in its first line, it is necessary to move the paper carriage with the totalisers 2 to 5, or the columns I to IV, respectively, into the operative position required at the time. This is effected by depressing the tabulator key 2| corresponding to the item to be booked. During the consequent movement of the carriage to the left, and therewith of the totalisers 2 to I, the cross totalisers I2 and I3 forming the complementary totaliser unit K, are automatically coupled to a dog 33a (Fig. 1) 01' that column totaliser 2 to I which moves into active position at the time, by means of the pick up bars l4, I5 (Fig. 3) of the slide II (Figs. 1 to 6) which carries the two cross totalisers I2 and I3, so that these partake in the movement to the left. In this operation the denominational wheels of the cross totalisers l2 and I3 are successively moved into driving connection with their respective master wheels 35 and 35 (Figs. 5 and 6) which are mounted to turn on a cross totaliser master wheel shaft 34 (Figs. 1 and 3 to 7) but are held against axial displacement. That column or dummy totaliser which is coincidently moved into calculating position, comes into driving connection with a master wheel 38 coordinated to all column totalisers (Figs. 3, 4, and 7) and secured on a column totaliser master wheel shaft 31. When the paper carriage, or the totalisers 2 to I, and the cross totalisers I2 and I3, move into active position, each column totaliser, through controlling earns 35, 40 and 4!, secured to the totalisers as required, acts on controlling levers 42 (Fig. 4), 43, (Fig. 5)), and 44. Thereby, in a manner to be described more in detail in connection with the total taking operation, the calculating mechanism is unlocked and the species of calculation in the cross totalisers is selected. The controlling lever 44 (Fig. 3) shifts a coupling sleeve 45 mounted to slide axially on the driving shaft 34, to engage the coupling teeth III or H2 at opposite ends of the sleeve with coupling teeth 46 or 41 connected to the cross totaliser master wheels 35 and 35, which are also arranged on the shaft 34. A link I02 pivotally connecting the controlling lever 44 to a coupling arm I03 (Figs. 4 and 9) transmits the movement imparted to the controlling lever 44 from the cams 4| on the column totalisers 2 to 1, to the coupling sleeve 45. In the case of the present booking operation, the teeth III and N2 of the coupling sleeve 45 must be engaged with the driving gears 35 and 36 at the same time, and therefore, the link I02 is removed and the controlling lever 44 is rendered inactive. In such instance, the coupling arm I03 which controls the sleeve 45, and is fulcrumed about a screw I08 in the casing of the calculating mechanism, is held in neutral position by a screw M inserted in a hole of its extension |03a and secured in a bracket L (Fig. 'I) on the casing of the calculating mechanism.

Before a tabulator key is depressed for releasing the carriage so that it moves to the left, as described, the species of calculation to be performed in the column totalisers 2 to 5 is selected by means of knob 48 (Figs. 1 to 4). Usually, the species is addition, and so the knob 48 is turned so that its index ||6 (Fig. 1) is on the mark A in the front wall 3| of the calculating mechanism. A tilting member ||1 (Fig. 7) is positively connected to the knob 48 and transmits the movement of the knob to a link I20 through a pin 8 engaging in a notch I IS in the link. The link is connected to parts |2| to I21, an arm I22 being equipped with a pin |2| at its upper end, and a slot 293 in the link I20 engaging over the pin. A spring I28 attached to the arm I22 and anchored to a stationary part of the calculating mechanism frame, maintains a connection between the arm I22 and the state control link I20 which is positive in one direction, and yielding in the other.

When the knob 48 is turned as described, an intermediate spur gear I21 is moved into the position illustrated in Fig. 7, as follows: The spur gear I21 is connected to a differential shaft 50 by claws I30 and a clutch disk |3I secured on the shaft, so that the spur gear can be displaced on the shaft but is held against rotation with respect thereto, and, in the position illustrated in Fig. '1, the column totaliser master wheel 38 is rotated through the driving shaft 31 to which rotation is imparted by a train of gears I21, I32, I33, and I34, and this rotation corresponds to addition.

For accounting and writing the items to be booked in columns I to IV, the corresponding calculating keys 20 are depressed, and the values introduced are entered in that column totaliser 2 to 5 which is in calculating position at the time, through the medium of a differentially driven spur gear 49 on the shaft 50 (Figs. 1, 1a, 3, and 4), and the master wheel 38 on the shaft 31, in conformity with the position of the calculating species knob 48. The operative connection of the shafts 50 and 31 is effected by reversing gearing including the gears I21, I32, I33 and I34, as will be described below with reference to total taking.

The mechanism for automatic total taking The balances calculated from columns I to IV of the form 25 (Fig. 16) in the cross totalisers I2 and I3 which form the complementary unit K (Fig. la) may be withdrawn by automatic total taking and typewritten in the columns V and VI of the form 25. Let it be assumed that first the item 125 in the cross totaliser I2 is withdrawn and written in the first line of column V of the form 25. At the same time, the cross totaliser I3 which indicates the complementary value 9999 875," must be automatically returned to zero. The complementary value must obviously not be written on the form.

In order that the cross totaliser I2 can be cleared, the dummy totaliser 6 must be moved into the corresponding active position, since it controls the cross totaliser I2. This is effected by depressing the 100 tabulator 2|. The ensuing movement of the carriage to the left is limited by the tabulator carriage stop (not shown) co-ordinated to the dummy totaliser 6,

which stop engages the column selector lever (not shown) co-ordinated to the depressed tabulator key. In this position, the hundreds denominational wheels of the cross totalisers I2 and I3 which have been moved by the dog 33a of the dummy totaliser 6 (Fig. 1) and the pick-up bars I4, I5, are engaged by the cross totaliser master wheels 35 and 36 (Figs. 3 and 7).

The control cam plates 4| (Figs. 5, 6, and 11) of the column totalisers 2 to 1 determine whether the denominational wheels of the cross totalisers shall be rotated additively or subtractively. The cam plate 4| is mounted to slide at the inner side of a front plate 5| (Figs. 5 and 11) of each totaliser 2 to 1 and may occupy three distinct positions. A rib 52 projecting inwardly from the front plate 5| engages in any one of three grooves 53 in the cam plate 4|. For the purpose of adjusting the cam plate 4|, a clamping screw 54, with a knurled end 55, (Fig. 5) extends through a slot 56 in the front plate 5| (Fig. 11). The position of the control cam plate 4| is indicated by a mark 51 on the cam plate, and marks 58 at both sides of a hole 58 in the front plate 5|. The three positions of the cam plate are: Addition, marked A, release or neutral marked D, and subtraction, marked S.

Since in the present example the value indicated in the cross totaliser I2 is additive, it must be withdrawn by subtraction. Therefore, the control cam plate 4| of the dummy totaliser 6 is adjusted for subtraction, S. When the paper carriage advances, the control cam plate 4| of this dummy totaliser 6 engages the tappet lever 43 (Figs. 3 and 7) which is a bellcrank. The control cam plate 4| turns the bellcrank 43 clockwise about its fulcrum 6| against the action of a spring 60 (Figs. 1 and 7) and a pin 62 at the lower end of the bellcrank engages a reversing lever 63 and a link 64. The link 64 is pivoted to a rocker 65 on a shaft 66, and the bellcrank 43, through the means described, turns the rocker anti-clockwise, and its movement is transmitted to an axially shiftable spur gear 68 by a slide 61, as follows: A pin 69 on the rocker 65 engages in a slot 10 of the slide 61, and a tooth 1| on the slide engages in a groove of the spur gear 68. The spur gear is mounted to slide on the shaft 50 and is held against rotation about the shaft by claws 12 engaging in grooves in the perimeter of a disk 13 keyed on theshaft.

When the spur gear 68 is shifted by the mechanism connected to the rocker 65, which turns anti-clockwise, as described, it moves out of mesh with a pinion 14 on the shaft 34 and into mesh with an idler pinion 15 mounted to rotate in the casing of the calculating mechanism and engaged with a driving spur gear 16 secured on the cross totaliser master wheel shaft 34.

The drive which for addition is from the differential shaft 50 to the cross totaliser master wheel shaft 34 through spur gear 68, and pinion 14, is now reversed for subtraction, since the shaft 50 now drives the shaft 34 through the spur gear 68, the idle pinion "I5, and the spur gear 16.

One end .of a link 11 is pivoted to the lower end of the bellcrank 43 and slides on a headed screw in the front wall BI of the machine (Figs. 1 and 2). The link 11 is shifted by the swinging motion of bellcrank 43 in the direction of the arrow C. The lower end 02 of a downwardly extending arm 33 of link 11 is provided with a triangular slot 34 through which extends a headed rivet 81 projecting from an offset lug of the selector lever (see also Fig. The selector lever 00 is mounted to swing laterally and to be shifted upwardly by means of a slot 00 and a headed screw (Fig. 7) extending through the slot. The screw 30 is secured in a bracket 03 and this is attached to a part 92 of the casing for the calculating mechanism by screws 3| (Fig. 1). In its initial position, the selector lever 05 is supported by gravity, the upper end of its slot 08 resting on the headed screw 00. Obviously when the carriage cam 4I (Figs. 5 and 6) wipes over the upper arm of the bell crank 43 (Figs. '7 and 9) to set the cross totaliser reverse gearing 68, 15, 14, 18 to "subtract, such cam and bell crank will shift the link 11 to the left to rock the lower end of the selector lever 06, about the pivot 80.

The resulting clockwise travel of the upper end of the selector lever 06 operates to position a forwardly bent lip 93 formed on a lateral extension 34 of the upper end of the selector lever 00, beneath the right hand one of a pair of adjacently located tails I00 (Fig. 8) projecting from the bell cranks and 95, respectively, to be described below. The selector lever 06 at its lower end has a laterally offset ing 91 provided with an inverted U-shaped slot 93. A headed screw 33 secured in the machine frame (Fig. 1) projects through the slot 30 whereby the selector lever is further guided. As the selector lever 05 is swung clockwise about the bearing screw 90 by the pin-and-slot connection 81, B4, to position its lip 33 beneath the tail I00 (Figs. 1a, 8) of the bellcrank 95, the lug 91 of the selector lever 06 is shifted to position the arm IOI of the inverted U-shaped slot 90 into line with the guiding screw 03.

Since, as described in the paragraph the normal calculating and typewriting operations etc., both cross totaliser master wheels 35 and 30 are driven together for the booking operation described, the control cam plate (Figs. 5 and 6) which operates the sleeve (Figs. 4 and 9) is not required in the dummy totaliser B and is dispensed with, as well as the lever 44 and the link I02 illustrated in Fig. 9 and omitted in Fig. '7. When the dummy totaliser 6 has moved into calculating position, its control cam 3! acts on the control lever 42 (Figs. 3 and 5) to displace a latch II3 whereby to release a normally effective totaliser locking mechanism II4, I I5, for operation.

Preparation of the total taking operation upon depression of the controlling members for the cross totalisers A bar I35 secured in the sub-frame I9 extends transversely across the machine (Fig. 10) and a controlling member or total key lever I36 for the cross totalisers I2 and I3 is mounted to swing about the bar and held against axial dis placement. The cross total taking key 23 for manual operation is secured to the front end of the controlling member I36. A stepped extension I30 projects from the lower side of the controlling member I30 for holding the member in its initial position and a spring I31 pulls the extension I33 against the rear side of a locking bar I39 which also extends across and is secured in the sub-frame I9.

A locking member I40 is fulcrumed on the con trolling member I38 at the left about a screw 552 which prevents lateral displacement of the locking member. A spring I connecting the members I38 and I40 pulls a tongue I42 of the locking member against the other side of the locking bar I33 and holds the locking member I40 in its initial position.

The rear end of the controlling member or total key lever I35 is laterally offset as at I44 and terminates in a second offset lip I43 which lies beneath the lower end of the selector lever 05 to raise the latter when the controlling member is depressed. Upon depression or the controlling member or total lever I30, the tail I45 oi the locking member I40 engages a lug I45 at the upper end of a vertical arm I41 extending from one end of a lever I48. The lever I4! is fulcrumed on a transverse cross brace I50 by a headed screw I40, and its inner end is equipped with a pin I5I engaging in a slot I52 at the inner end of a similar lever I53 fulcrumed on the cross brace I50 at I54. The opposite end I56 of the lever I53 is bent upwardly and equipped with a lug I55 at its upper end for cooperation with parts to be described below. The cross brace I50 has a lug I51 at one end secured to a bracket I50 in the sub-frame I8 by screws I58 (Fig. 1) and its other end is secured to the stationary locking bar I33 by a pair of tongues IGI (Fig. 10) and screws I52.

When the controlling member or total key lever I36 is depressed the tongue I42 of the locking member I40 engages in a groove I33 in the locking bar I39 under the action of the spring I, holding the locking member I40 and the controlling member I36 in depressed positions. When the controlling member I35 is depressed,

a shoulder I54 on the member engages a pin I51 riveted into an ear I 55 at the outer end of a lever I56. The lever I56 which is fulcrumed on the inner side of the front transverse bar of the sub-frame I9, at I53 (Figs. 1 and 10), is operatively connected to another lever I1I (Figs. 1, 10, and 12.). This lever which is also fulcrumed on the inner side of the front transverse bar of the sub-frame I9 at I12, is bent at its outer end, as at I13 to overlie an offset I14 of a clutch disabling lever I15 journaled on the fulcrum bar I35 alongside a controlling member I15 (Fig. 12)

, for the total taking from the column totalisers 2 to 5 likewise journaled on the bar I35. By a spring I11 the clutch disabling lever I15 is urged anti-clockwise about the bar I35, and its rear end I15a cooperates with a clutching pawl I13 whereby the eccentric element, here designated SM, 502, is held disengaged from a rotating shaft 504. The total taking controlling member I15 (Fig. 12) for the total taking from the column totalisers 2 to 5 has 9. lug I19 acting on the offset I14 of the clutch disabling member I15. The tail end of the column totaliser total taking lever I15 can act on a slide I which has been shown only partly and on a lever 282, Fig. 12, as will be described.

When the total taking key 23 (Fig. 10) for the cross totalisers is depressed, the total taking key lever or I38 is swung about the bar I35 clockwise against the action of its spring I31, and the locking member I40 is moved in the same direction by the spring I. The tongue I 42 of the accuses locking member I40 slides off the locking bar I39 and then, at the end of the swinging movement, engages in the groove I63 of the lockin bar I39 under the pull of spring I4I. By these means, the cross totaliser total taking key lever I36 is held depressed.

During the swinging of the members, the rear end I45 of the locking member I40 moves into active position with respect to the lug I46 on the lever I46 by which it is influenced toward the close of the total taking operation, as will be described. The tail I43 of the depressed total taking lever I36 bears against the lower end of the selector lever 86 which, as described, has already been turned clockwise, and raises it. The lip 93 (Figs. 7 and 8) at the upper end of the lever 86 now engages the tail I of the bellcrank 95 and the bellcrank together with the mechanism under it control are operated as will be described. If, however, the control cam plate 4| in one of the column totalisers 2 to has been shifted to E, and this totaliser is in calculating position, the edge 850 (Figs. 1, 2, 7, and 9) of the inverted U-shaped slot 98 in the lug 91 of the lever 96 engages the stem of screw 99 and prevents further depression of the total taking lever I36.

At the same time the shoulder I64 on the depression of the total taking lever I36 engages the pin I61 at the outer end of the toggle lever I65, IN to press the bent end I13 upon the offset I14 at the i1 ont end of the clutch disabling lever I15, to rock the clutch disabling lever clockwise against the tension of spring I11, whereby the rear end I15a of the clutch disabling lever moves clear of the clutching pawl I18. Thereupon a spring 503 engages the clutch pawl with the gear T to couple the eccentric element 50I, 502 with the shaft 504 rotated from the motor 24.

The zero stop mechanism for the cross totaliser 12 The bellcrank 95 (Figs. 1a and 8) is fulcrumed on the casing of the calculating mechanism at I8I. A link I82 is pivoted to the upper arm of the bellcrank at I83, its other end being connected at I84 to a lever I85. The lever I85 is fulcrumed on the rear wall of the calculating mechanism casing at I86 and its forked upper end I81 engages a pin I88 on a slide I89. The slide is slotted at I90 and a screw I9I in the rear wall engages in the slot for guiding the slide which is supported by a pin I92 in the rear wall. A spring I93 turns the lever I85 about its pivot I86 in anti-clockwise direction and the lever moves the slide I89 to the left. This movement is limited by the end of the slot I90 bearing against the screw I9I and defining the initial position of the corresponding parts.

A flap I95 is mounted to turn about a shaft I94 but held against axial displacement and its tail I96 is engaged with the low inner end I91 of the slide I89 "by a spring I98, such engagement serving to press the slide against its supporting pin I92. The shaft I94 is supported by a bracket I91a (Fig. la) secured to the front wall 8| of the calculating mechanism by screws I98a. The flap is held against lateral displacement on the shaft I94 between a flange I99 (Fig. 6) of the bracket I91 and an annular check 200 on the shaft I94. A zero stop 203 is secured on an upwardly flanged portion 20I of the fiap I 95 by screws 202 which zero stop acts on parts of the cross totaliser 92 in a manner to be described below,

A lever 205 (Figs. 6 and 8) is keyed b hub 206 on a release shaft 204 arranged suitably in the calculating mechanism. A push rod 201 is pivotally connected to the upper end of the lever 205 at 208. The free rear end 209 of the push rod is reduced and lies beneath the slide I89. An inclined face 2I0 is formed on the push rod for cooperation with the slide I89, for a purpose which will be described. The rear end 209 of the push rod is guided in, and supported by, a recess in the rear wall of the calculating mech anism. An inclined face 2| l .on the slide I89 cooperates with the tail I96 of the flap I for a purpose to be described below.

The zero stop mechanism for the totaliser 13 A bellcrank 96 similar to the bellcrank 95, is fulcrumed about the same headed screw I8I (Fig. 8) in the calculating mechanism. To the upwardly projected arm of the bellcrank lever 96 is pivoted a link 2I3 at 2 I2 and the other end of the rod is pivoted to a lever H5 at 2. The upper forked end of the lever 2I5 fulcrumed on a headed screw 2I6 in the rear wall of the calculating mechanism, embraces a pin 2I8 on a slide 2I9. The slide 2I9 is mounted for longitudinal displacement along the. rear wall of the calculating mechanism by a slot 220 and a screw 22I secured in the rear wall. It is further guided by a pin 222 secured in the rear wall. A spring 223 engaging the lever 2I5 swings the lever 2 I5 counterclockwise about its fulcrum screw 2I6, and the lever pushes the slide 2I9 to the left. These movements are limited by the end of the slot 220 'bearing against the screw 22I in which position the parts mentioned and the members connected to them are in their initial positions. Another flap 224 is mounted to swing about, but held against axial displacement on, the shaft I94 and its tail 225 is in operative connection with a nose 226 of the slide 2I9. A spring 221 engaging the tall 225 of the flap 224 holds the tail against the nose 226 of the slide 2I9 and by these means the slide 2I9 is held against the supporting pin 222. .A flange 228 (Fig. 1a) of the bracket I91a and an annular check 229 secured on the shaft I94 hold the flap 224 against lateral displacement on the shaft I94. A zero stop 232 is secured on an upwardly extending front flange of the flap 224 at 23I, which stop can act on parts of the mechanism of the cross totaliser I3, as will be described. A lever 233 is secured with its hub 234 on the release shaft 204 which has been described in the paragraph The zero stop mechanism for the cross totaliser I2. A push rod 236 is pivotally connected to the free end of the lever 233 by a screw 235. The free end 231 of the push rod is reduced and extends beneath the slide 2I9. An inclined face 238 is formed on the push rod 236 for cooperation with the slide 2I9, for a purpose which will be described. The push rod 236 is guided in, and supported by, a recess in the rear wall of the calculating mechanism. An inclined face 239 on the slide 2I9 cooperates with the tail 225 of the flap 224 for a purpose to be described be- The cross totalizer release shaft 204 on which are mounted the usual unlocking levers 240 (Figs. 5 and 6) for the unlocking of the calculating wheels of the cross totalisers I2 and I3 is operatively connected to the column totaliser release shaft I I5 by levers 24I and 243 and a pin-and-slot connection 242. The calculating mechanism un locking lever 244 for the column totalisers is keyed on the shaft H5.
